Most fishing umbrellas tend to be round, but Ron Thompson has bucked the trend with the Quattro square brolly.
It has a diameter of 2.5m, offering ample protection against the rain, and its straight sides make it very good when positioned close to the ground, which can be done simply, thanks to the easy-to-use angle tilt system.
The ground spike is very strong and is fully telescopic, allowing you to position the brolly high in the air should you need to.
It comes supplied in a nylon storage sleeve. Expect to pay around £35.
